Panel Providers and Limesurvey - your experience?

Most of the time the link (from the panelprovider) can be used once, so the security is done on their part.
They just pass the respondent to the survey hosted in your Limesurvey.
The link itself will not be shown to the respondent.
If they have completed the survey the ID is send back and recorded as complete on the panelproviders end.
So if that same respondent wants to participate again, their system will not allow to continue and the redirect itself to the limsurvey survey will not work.
Also the respondent will receive only once their incentive.
So there will not be a reason to fill it more than once.
If they do, you can just easily clean (if you can fill int the survey more then once) it afterwards, every double ID will be removed.
Hope that helps, Dennis

But you cannot really validate that panelists don't modify those IDs and take the survey multiple times.

The only way to do this is e.g. loading all panel user IDs into Limesurvey and using the ID as token at Limesurvey.
If you set up Limesurvey to use each token only once, then the token will be marked "used" after submit.

This is rarely used because the work-flow without tokens usually works fine for the reasons mentioned by TwentyTwo.

New plugin event 'beforeSurveyPage' allow us to create token on the fly.

Some provider offer too API json for information from user.

A solution ca be:
- User come with "panel user id"
- Testing if this panel user id exist in token table :
- if yes : go to the survey with the good token
- If no : search with the API for extra user information and create a token with all information
- redirect to the good token

...and for the token you are using the passed panel user ID to prevent duplicates and double registrations later?

No,

Actually : i create token with attribute_1 to panel_uid. Whan come with a panel_uid : search on the token table for corresponding token. If exist : redirect, if not create and redirect.

Then token is really hardest to find.
